Minneapolis, in the county of h Improvements in Shock-Loaders; and do following to be a full, clear, and eirffct descript on of the l11YIltlO11,SL1Ql1.1-S will en:

able others skilled in the art to which it appertains to make and use the same.

My invention relates to shock l -iders of that type wherein shocks of grain are picked up in success on by a large fork and are thrown iarward into the rack or box of a vehicle which is moved forward either by.

horses or by-traction power. Particularly, the invention is dlrected to the provision of an improved means for operating the fork for picking up the shocks. Generally stated, the invention consists of the novel devices and combinations of devices hereinafter decribed and defined in the claims. In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views. Referring to the drawings, Figure 1 is a side elevation showing a shock loader having my invention incorporated therein; Fig. 1 is a fragmentary plan viewshowing the front end portion of the rack or body of the carrying vehicle; Fig. 2 is-a detail view in side elevation showing one of the fork ac-' .tuating eccentrics,

some parts thereof being broken away, and showing also portions of clutch inechanism for operat- Fig. 3 is a sectional view taken approximately onthe line 0 aficn 2, some parts being broken away; Fig. 1 is a view corresponding to Fig. 3 but illustrating different positions of the parts of t 1e clutch, some parts being broken-away, Fig. 5 is a detail View chiefly in elevation but with some parts sectioned tripping cam ring, a clutch pin and a cooperating stop tion taken approximately on the line 02 m on Fig. 5and Fig.7 is a view corresponding to Fig. 6 but illustrating different posi tionsoftheparts.

'Atjthe rear of the vehicle body is'a hinged gate 7 and. zi'transversely extended draft beam 8 as "which draft horses, located on opposite sides of the machine may be 6 hitched, in thewell known way, to draw the carrying-.-i-ehicle forward. i v

The loadingfork 9,.which is axlarge heavy structure of the usual or any suitable construction, is. pivotally connected aor hinged at-10 'to the front portion of the raclr'l.

The numeral 18 indicates aclutch huhgo which, in the present'instance, is a hub "of one of the eccentrics 13. llfounted for endthe hub 18, parallel to the axis of the shaft 12 by eccentrics to said shaft is a clutch bolt 19 that is adapted to 5 seat 20* formed in the hub of-a large sprocket 20 which is arranged to rotate on the shaft 12, but is held against lateral movements. j

A coiled spring'21 seated in the hub 18 arm 22'of the said the said bolt with the" said seat 2O but this engagement is normally prevented by a cam ring 23 seated for rotary-movements .on the said hub 18. This cam ring 23 is provided with a radially projecting arm 24 and wit-ha reduced cam surface 28*. Itshould be here noted that theclutchbolt 191s provided with a notch 19* in which the cam ring 23 is arranged to 1 The arm 21 is connected by a chain 25, or other connection which is flexible at shown in r then held 3, bythe LIB .

The sprocket chain 29 runs over a sprocket wheel mounted-to rotate on a suitable bearmgon the adjacent side of the rack 1 and provided on its hub with a smallerv sprocket 31. Alsp'rockehchain 32 runs over the sprocket 31 and over the larger sprocket- 20, already described. When the machine is being driven-forward, to pick up a ,shock, the fork -9 is down upon the ground, as Fig. 1, and the clutchbolt 19 is in its inoperative position shown cam ring 23, so that the en' glne ,driven sprocket 20 then continues to' the fork has been run without effect.

It is important to here. factthat the eccentrics l3 first operate on the fork .With-.-a very short. leverage, and '-'that with gradually increasinglength of l everage, greater power is rendered effective at slow speedto impart the initial upward creasing or accelerated speed.

When the fork is thus released from the. driven sprocket, it will drop-by gravity back into its ,lo wer'ed or operative position ready to pick up another shock of grain. The movements of the fork are, therefore, very quickly completed so that shocks of grain quite close together may be picked up. It

1s here further important to note that the engine used to operatethe fork has no other function to perform in as'much as the ve-" hicle is moved forward ence, a small and very light engine may be employed for operating the fork and the speed at which the fork will be operated may be very rapidly performed and'isindependent of the advance movement of the machine. The automatically tripped clutch positively prevents breakage of the parts and all the operator has to do is to trip the clutch into action when the shock is properly loaded on the fork.
